Parents Urge Amy Winehouse & Husband to Get Help

The parents of Amy Winehouse's husband Blake Fielder-Civil have made an impassioned plea for their son and the singer to stop taking drugs before one or both of them die.

"We are in hell," Georgette Fielder-Civil told PEOPLE, adding, "people who take drugs don't care about other people [but only care about their next fix]."

"My emotions are up and down, every minute of the hour," she said, sounding distraught in the phone interview. "We're riddled with guilt, we question our parenting ... Everything goes through your head. Do you wait until they die? You think you should have done this, you should have done that."

Georgette Fielder-Civil also spoke to the BBC: "I think they both need to get medical help before one of them, if not both of them, eventually will die."

Fielder-Civil's husband, Giles, also noted that his son and Winehouse – recently photographed with blood on her clothes, face and shoes – were "very close ... If one dies through substance abuse, the other may commit suicide."

Both the Fielder-Civils and Winehouse's father, Mitch Winehouse, spoke out as both families grapple with the reality of the young couple's drug use.

Giles Fielder-Civil told the BBC that he believed his son and daughter-in-law used cocaine, crack cocaine and possibly heroin, and added: "Georgette and I both believe that they are drug addicts, and they don't believe they are. I think they believe they are recreational users of drugs, and they are in control, but it seems to Georgette and I that this isn't the case."

The couple went on to propose that fans should help by refusing to buy Winehouse's records. "It's a possibility, to send that message," they said.

But Mitch Winehouse said he believes such a boycott "won't send any message to Amy at all, unfortunately."

Instead, he said, "The only way out of this is not sectioning them, not locking them up. At some point they are going to reach rock bottom."

Georgette Fielder-Civil told PEOPLE that she had a "very emotional" phone call with the elder Winehouse the other day and both parents, "want to help ... we just don't know what to do for the best."

As for last week's photos of the young couple, the elder Winehouse told the BBC, "I thought that here are two people that are completely out of control. As a parent it was sickening, worse than sickening."
